 <em>r.threshold</em> It finds optimal threshold for stream extraction. 
 
 <h2>NOTES</h2>
-<p>It allows to find the optimal value of upslope area in order to extract the river network using r.stream.extract or r.watershed. Real streams depend on rainfall and infiltration rate, i.e. the same topography in different parts of the world yields different real stream networks. This approach provides a best guess about what makes sense when looking only at the DEM.
+<p>Finds a first tentative value of upslope area to be used as input to extract the river network using r.stream.extract or r.watershed. Real streams depend on many factors, such as rainfall, infiltration rate, geology, climate etc. i.e. the same topography in different parts of the world yields different real stream networks. This approach provides a best guess about what makes sense when looking only at the DEM.
